Smittia, Hincks. 



Smittia marmorea, Hincks. (PI. IX. fig. 6.)

 Hist. ser. 5,'iii. (1879) p. 39. 



Several fine specimens of this form occur on Mr. Johnson's 

 slides ; and they enable me to speak with confidence as to its 

 complete distinctness from S. cheilostoma, Manzoni. 



Seven British species of this genus have been described. 

 Lepralia marionensis, Busk (from Marion Island), belongs to 

 it, and probably L. galeata, id., from the Falkland Islands. 



Range of Distribution. Cornwall ; Guernsey ; ? Bay of 

 Naples j Madeira (J. Y. J.). 



Phylactella, Hincks. 

 Phylactella lucida, n. sp. (PI. X. fig. 4.) 



Zoceeia somewhat flask-shaped, smooth, and subhyaline, 

 ovate below, rather tumid, distinct, the peristome much ele- 

 vated, forming an erect, neck-like extension of the cell, sur- 

 rounding the front and sides of the orifice ; margin thin, 

 bearing 5-8 spinous projections, the central one stout, and 

 supporting a minute oval avicularium ; a groove round the 

 base of the peristome ; orifice suborbicular. 



Loc. Madeira, on shell (/. Y. J.). 



Before the development of the raised peristome the zooecium 

 is simply ovate, with a plain suborbicular or slightly elliptical 

 orifice. When fully formed, the erect neck-like extension 

 nearly equals in length the rest of the cell ; it is not continued 

 round the upper margin of the orifice. The edge is slightly 

 everted, and bears a variable number of spinous projections, 

 and an aviculiferous process in the centre. The texture is 

 very delicate, and the surface perfectly smooth. 



This form is referred with some doubt to Phylactella ; it 

 differs from the other known members of the genus in the more 

 erect and tubular character of the raised peristome, and the 

 presence of aviculiferous processes. 



Besides the species already noted as occurring in Madeira, 

 the following have been identified amongst Mr. Johnson's 

 specimens : — 



Aetea recta, Hincks. 



Cribrilina punctata, Hassall. 



Membraniporella nitida, Johnston. 



Range. Kara sea ; North sea; Britain (passim); France, 

 S.W. ; Bay of Gibraltar ; Madeira.
